RAIL JACK.

Application filed September 30, 1924:. SerialNo. 740,808.

To all 'io/71011@ @'15 may concern.'

Be it known that l, Tetonas Rav, a subject of the King` of Great Brita-in, residing' at Slegas, Province of ll ew Brunswick, and Dominion of Canada, have invented new and useful Improvements in Rail Jacks, of which the following is a specification.

rl`his invention relates to rail jacks and has for an object the provision of a jack which may be engaged with both rails of a trac; and operated to simultaneously move the track rails laterally.

Another object of the .invention is the provision of a jack of this character which may be adjusted for the height of the rails and operated to move the rails with a minimum amount of time and labor.

lilith the above and other objects in view, the invention further includes the following novel features and details of construc-V tion, to be hereinafter more fully described,

illustrated in the accompanying drawings and pointed out in the appended claims.

ln the drawings Figure 1 is a sectional view taken transversely of a track with the invention in position for use.

Figure 2 is a top plan view of the same. y

Figure 3 is a section taken.longitudinally of the j ack with the arms removed.

Figure 4r an enlarged sectional view on the line 4-l of Figure 1.

Figure is a similar view on the line 5-5 of Figure 2.

Referring.,r :in detail to the drawings wherein like characters of reference denote corresponding` parts, the reference character indicates a supporting base for the jacl; which is preferably formed of a channeled member which includes spaced parallel side plates having inclined upper edges 11. Secured transversely across the bottom of the base are angle irons 12 which project beyond the opposite side edges of the base and act as stabilizers.

rlhe hase 10 is designed to be placed between the track ties and acts as a support for a casing which includes spaced parallel side plates 13. The lower edges of these plates are provided with inwardly offset flanges lt so as to provide shoulders 15 for engagement with the upper inclined edges l1 of the side plates of the base 10. The casing may thus be supported in al manner to adjustits height with respect to the rails of the tracky The side plates .13 are connected by means of bolts 1G and are spaced apart by spacing sleeves 1? the said plates forming bearings for shafts i8 and 19. The shafts 18 have secured thereon between the side plates 13, gears 20, while also secured upon these shafts 18 upon the outsde of the plates 13 are gears 2l. The gears 2l are engaged and driven by a pinion 22 which s mounted upon the shaft 19 between the plates 13, while also mounted upon the shaft 19 and straddling the pinion 22 is the bifurcated end 23 of an operating lever 24. This lever has pivotally secured thereto oppositely disposed dogs 25 which are adapted to engage the teeth of the pinion 22 whereby operation of the lever 2li will rotate the pinion, the direction of rotation depending upon which of the dogs is engaged with the gear 22. By this means the gears 21 may be rotated through the gears 20 and shafts 13.

Located upon opposite sides of the casing and supported by the gears 21 are spaced arms 26 whose lower edges are provided with rack teeth 2? which engage the teeth of the gears 22, whereby rotation of the gears will move the arms laterally. rlhe arms 26 are of sectional formation, the sections being adjustahly connected by a pin and slot connection as indicated at 23, while ,the arms are held spaced apart by spacing` pinicns rl`he pin and slot connection 23 between the sections of the arms also provides a pivotal connection between these sections and in order to limit pivotal moveinent in one direction, one section of each of the arms has extending therefrom ay laterally disposed lug which engages 4beneath the other section of the arm and prevents pivotal movement in one direction. The outer ends of the arms 26 are adapted to engage beneath the heads of the rails R.

In the use of the invention, the base 10 is positioned between the ties and thecasing; mounted upon the base with the arms adjusted through the pin and slot connection 28 so as to engage the webs of the rails lt. The casing is adjusted upon the inclined edges 11 of the post l() so that the opposite ends of the arms 26 will engage beneath the heads of the rails R. Operation of the lever 24 will then rotate the gears 22 to cause the arms to be moved vertically and horizontally, vertical movement being effected by the increased thickness of vthe arms 26. yThis vertical movement acts tol raise the rails and ties sufficiently to permit them to be moved horizontally over the -ground, this horizontal movement being etiiccted simultaneously with the lii'tingA movement. The direction of movement is governed by the particular dop` E which engages the pinion 22.

The invention is susceptible of various changes in its form, proportions and minor details off construction and the rightis herein reserved to make such changes as properly fall within the scope of'the appended claims. i

Having Idescribed the invention what is claimed is l. A track jack comprising transversely disposed rail engaging arms, rack hars included in said arms. a housing, gears rotatably supported by the housing;` and en- ,eaginpj the rack bars and means whereby the ,Qears may be operated to move the arms vertically and horizontally to adjust the rails laterally.

2. A track jack comprising` a supporting base including' spaced parallel plates havino; inclined upper edges, a housing, spaced plates included in said housing, longitudinally disposed shoulders provided along the lower edges ot the housingplates for sliding engagement with the inclined edges vol' the supporting base, gears rotatably mounted upon the outside of the housing, rack bars engaging the `'ears, means at the opposite ends of the rack bars for engagement with the rails of a track, an operating lever and means located within the housing and operatively associatingthe lever and ,gears whereby the rack bars may be moved laterally.

A track jack comprising a supporting' base hzwing` an inclined top, arms disposed transversely of Lthe track above the base and 'engaging' the rails of said track, a member mounted for vertical adjustment upon the inclined top of the base, means operatively associating the member and arms whereby the latter may be moved vertically and hori- Zontally and means whereby the arm movino; means may be actuated.

In testimony whereof I ah'iv my sirrnarurc.
